LIFE-GUARD FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Apr. 19, 1910.

Application filed January 6, 1910. Serial No. 536,738.

1 '0 all whom it may concern:

Be it known that I, GEORGE A. PARMEN- TER, a citizen of the United States, residing at Cambridge, Massachusetts, have invented certain new and useful Improvements in Life-Guards for Railway-Cars, of which the following is a specification.

My presentinvention relates to improvements in fenders or guards for railway cars of the type known as trip and drop scoop, and is particularly designed for use on double or swinging truck cars.

In a prior application filed by me in the United States Patent Office on the 27th day of March 1909, Serial No. 486136, I have shown and described an improved fender of the trip and drop scoop type which has proved eminently satisfactory, but I have found that some roads have their car platforms provided with fixtures or attachments that interfere to a greater or less extent with the use of a centrally disposed locking bar and resetting devices.

I have aimed in devising my present invention to provide a fender particularly adapted to cars of this character, and one in which extreme simplicity and durability are attained, and I have also aimed to support the basket in such a way as to relieve it as far as possible of the shocks 0r jars encountered by the truck in passing over rough or uneven tracks.

\Vith these and other objects in view the invention comprises the novel features of construction and arrangement and combination of parts hereinafter described and particularly pointed out in the appended claims.

A fender constructed in accordance with my invention is illustrated in the accompanying drawings in which Figure 1 is a plan view showing a sufficient portion of a car platform and sills in outline to illustrate the application of the fender thereto. Fig. 2 is a side elevation. Fig. 3 is an enlarged plan view of one of the hangers for the scoop or basket. Fig. 4 is a section on line 4, 4, of Fig. 3. Fig. 5 is a side elevation of the same, and Fig. 6 a front view. Fig. 7 is a fragmental front view of parts of the device.

Referring by reference characters to this drawing the numeral 2 designates the car platform and 3 the sills. The swiveled truck frame is indicated at 4 having the usual cross bar or pilot board 5 provided with brackets or hangers 6 with hooked or recessed portions 7 in which the rear cross bar or member 8 of the scoop or basket 8 is pivotally or rotatably seated.

The scoop is provided with upwardly extending arms 9, to the upper ends of which arms are pivotally connected the ends of a curved bar 16, which I call a radius bar and which is curved or formed in the shape of the are of a circle which has for its center the pivotal axis of the truck. The ends of of the bar are preferably turned inward, as shown at 16 so as to give a maximum length to the curved portion, and the pivotal connection is preferably effected by mounting these inwardly turned portions in eyes 10 in the upper ends of the arms 9.

Secured to the undersides of the sills 3 are front and rear metal bars 11 and 12. The extreme end of the rear bar 12, which is longer than the front bar, is doubled upon itself to form a recess in which is pivotally mounted the end of a rocking lever 13 indicated at 13. The main portion of this rocking lever is depressed below its pivot to bring it approximately on a level with the upper ends of the arms 9, and it carries at its inner end a U-shaped or forked bracket 14, between the arms of which are j ournaled two anti-friction rollers 15 and 15 which engage or bear against the front and rear sides of the curved. or radius bar 16.

A sliding locking bar 17 has its rear end pivotally connected to the lever 13 considerably to one side of the center of the car platform while its front end is slidingly supported by a guide supported by the bar 11.

The locking bar 17 has a laterally extending shoulder or offset 17 a which is designed to rest behind and engage a shoulder formed preferably by the edge of the guide as indicated in Fig. 1, in which position the locking bar will hold the lever 13 pressed backward and through the bracket 14 and rollers and radius bar, hold the basket or scoop elevated in the position shown in Fig. 2. In order to hold the bar 17 with its shoulder in looking engagement with the guide, I provide a spring 18 which has one endconnected to the bar 17 and its other end to the bar 11, the spring extending diagonally so that it not only tends to swing the bar 17 toward the center of the car and bring and hold its shoulder into locking engagement with the guide, but also, when the bar is moved to disengage said shoulder, tends to draw the bar forward and thus assist the action of gravity in causing the scoop to drop quickly.

In order to impart a lateral motion to the bar to thus unlock or release it, a bell crank lever 19 is pivoted on a bracket arm 20, one arm of this bell crank lever being connected by a link or rod 21 with an upwardly extending arm 22 carried by the top bar of the swinging trip frame near one side or end thereof. The other arm of the bell crank lever is provided with an elongated slot 19 which is engaged by a pin or projection 17 on the bar 1?. Normally, the pin lies near the rear end of the slot and when the trip frame is swung rearwardly the pull upon the link will rock the bell crank lever and cause the slotted arm to swing outward toward the side of the car, and, through the pin connection, pull the bar 17 sufficiently to one side to disengage the locking shoulder.

The slot in the arm of the bell crank is made of sufficient length to allow full forward movement to the bar to drop the scoop or basket. The slot is made of such a width as will permit the trip frame to be swung forward without binding on the pin.

For the purpose of resetting the scoop or basket, I provide a depressible treadle 23 in convenient reach of the motorman, the lower end of which is connected to a flexible element such as a chain 24 passing over a pulley 25 and connected (preferably by a rod) with oneend of a lever 26 which is pivoted on a bracket or hanger 27 depending from the sill of the car. The other end of this lever is connected by a link 28 with the forked bracket 14, so that as the treadle is depressed the lever will swing to pull the forked bracket back and through its connection with the curved bar cause the scoop to be lifted. At the same time the locking bar 17 is drawn rearwardly until its shoulder is brought into locking engagement with the edge of the guide and the parts held in reset position.

In order to relieve the basket as far as possible of jars or shocks due to passing over rail joints or rough tracks, I provide the special form of hanger shown more in detail in Figs. 3 to 6. In this the bracket 6 is provided with a vertical guideway having overhanging flanges in which guide way is slidably held the T shaped head 7 of the hanger 7.

The guideway of the bracket 6 has a closed lower end or abutment as indicated at 29 and the hanger 7 has a recessed rear face provided with a closed upper end or abutment 30 asclearly shown in Fig. 4. Within this recess and between the abutments is located a helical spring 31 which causes the hanger to be elastically supported.

The hanger is retained in the guideway by a cap 32 fitted thereon the upper end of which is secured in place by a bolt 32 which passes through the cap, bracket and pilot board as shown.

The rear bar 8 of the basket is preferably constructed of angle iron as shown and is retained in the recess of the hanger in which it pivots by the angularly turned end 33* of a bolt 33 which passes through a part of the bracket, such as an ear 6 and the pilot board.
